Water Modelling-Palaeo Stochastic Climate Data: 10,000 Replicates for Greater Sydney

Greater Sydney and surrounding regions are covered by this palaeo stochastic climate dataset. It includes 10,000 replicates of 130-year daily data for rainfall and potential evapotranspiration, generated using observed and palaeo climate data by University of Newcastle researchers. The data was used in modelling for the Greater Sydney Water Strategy.

Use Cases

• Simulate long-term water availability based on 10,000 stochastic replicates of daily climate data.
• Assess drought and flood risks using 130-year synthetic rainfall and evapotranspiration sequences.
• Calibrate hydrological models for the Greater Sydney area using combined observed and palaeo climate data.
• Perform climate stress-testing for water infrastructure planning based on stochastic climate scenarios.

Strengths

• Contains 10,000 stochastic replicates, providing a broad range of plausible climate scenarios.
• Each replicate covers a 130-year period of daily data for two key hydrological variables.
• Data generation incorporates both observed records and palaeoclimate information.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
